Pi0 and Pi0w GPIO layout map with landmarks

After counting pins many times to figure out where to wire up a Pi0 / pi0 Wireless it occurred to me that there might be some landmarks on the printed circuit board that would make it easier to find the desired GPIO pin without counting. The photos below are my attempt at this idea, and it does work, though it would be much better if the Pi folks had added a few silkscreened labels for this purpose.  Next rev, perhaps?

If you print these: these look good at 150 dpi in color, or as large as you can go in black and white.

As always, pin 1 is closest to the SD card slot.







postscript: I scavenged the board images and GPIO layout diagrams from the internet, so I cannot claim any ownership of the final composited image, just the idea. Instead of trying to stake a claim, however, I'd just enjoy if people could take this idea and make it better, perhaps improving the printability of the resulting image (the circuit board is awfully muddy on my printer).

Panasonic TH-42PX75U Plasma TV review: input lag and upscaling tested using the piLagTesterPRO

Image
This 720p Plasma TV from 2008 is very unique and quite nice in many ways. It used to retail for around $1300. If you can find one it's a great choice for retro gaming.  Overview/Image quality This is a plasma TV, which generally means at least the following: nearly infinite viewing angles, and jaw dropping weight. That's true in this case as well. This 42" model weights 75lbs.  At native resolution (720p) this TV crops 20 pixels off the top/bottom and 30 off the sides. 480p/i crops 20 pixels off all sides. Both modes have aliasing, too, though it's not too bad. There's really no excuse for aliasing on a TV this big: you know the panel was designed specifically to be a tv. Why not hit 720p exactly? And as for 480p/i, they could have at least offered a zoomed out mode with black borders and 1:1 pixel mapping. But no such luck. There are zoom/stretch options to crop even more, but none that crop less. While the native resolution supposedly is 1366 x 768 it does accept

piLagTester PRO order page

The piLagTesterPRO measures your monitor's input lag and response time. It is a cheap, full featured add-on to the Raspberry Pi; I provide the sensor and required software, you provide the Pi (a $5 pi Zero is more than sufficient). Although it has a DIY aesthetic, it is quite functional and in fact offers quite a lot more features than the commercial alternatives (Leo Bodnar and the Time Sleuth), and has been tested with over 40 TVs, including 4k models .  Here's what it looks like in action: The pi draws a black background, and then roughly once a second displays a set of target rectangles (top/middle/bottom). You place the sensor over the desired target, and the piLagTester measures the monitor's response starting from the moment the frame of video data is sent over the Pi's HDMI port. This is plotted in the graph, which is sideways for space reasons. The lag tester measures two thresholds. In red it shows how long it takes for the monitor to start displaying t

How to pause animation in PowerPoint

If you have a long animation looping animation that you want to be able to pause and then resume, there's an easy way to do so with the keyboard. Press the 1 key, which puts you in the mode where you can type in a slide number to jump to. In this mode, all animation is paused. To get out of this mode without jumping to another slide press the ~ key. There are lots of keyboard shortcuts in Powerpoint; press F1 to get a list. Note that one of them is listed as "pause" (S key or + key) but this doesn't actually seem to work in all the situations that the trick described above does. Tested an known to work in PPT 2003.
